Once installed, the APX 1500's level and clip indicators are designed to keep you informed of performance levels at a glance.
The APX1500 amplifier supplies massive power with plenty of headroom to drive any passive speaker.

The APX1500 also contains low-noise cooling fans to prevent overheating and high-current toroidal transformers for the lowest possible noise floor.
